Background for a gamma-ray satellite on a low-Earth orbit
Hernanz, M.; Cumani, P.; Kiener, J. +2 more
The different background components in a low-Earth orbit have been modeled in the 10 keV to 100 GeV energy range. The model is based on data from previous instruments and it considers both primary and secondary particles, charged particles, neutrons and photons. The necessary corrections to consider the geomagnetic cutoff are applied to calculate …
An automated approach for photometer and dust mass calculation of the Crab nebula
Sauvage, Marc; Nehmé, Cyrine; Kassounian, Sarkis
Ample evidence exists regarding supernovae being a major contributor to interstellar dust. In this work, the deepest far-infrared observations of the Crab Nebula are used to revisit the estimation of the dust mass present in this supernova remnant. Images in filters between 70 and 500 µ m taken by the PACS and SPIRE instruments on-board of t…
A robotic pipeline for fast GRB followup with the Las Cumbrés observatory network
Cucchiara, A.; Steele, I. A.; Marongiu, M. +9 more
In the era of multi-messenger astronomy the exploration of the early emission from transients is key for understanding the encoded physics. At the same time, current generation networks of fully-robotic telescopes provide new opportunities in terms of fast followup and sky coverage. This work describes our pipeline designed for robotic optical fol…
Designing large pixelated CdTe detection planes for hard X-ray transients detection
Bouchet, Laurent; Mate, Sujay; Bajat, Armelle +10 more
In this paper, we discuss the need for very large detection planes for the detection of hard X-ray transients in the multi-messenger era, started with the quasi-simultaneous detection of GRB 170817A by Fermi/GBM and INTEGRAL/SPI and the gravitational waves event GW 170817, detected by the LVC collaboration. After pointing that current and future i…
